/*
  Biotech.Net Web Gallery - "the bench instrument", same chassis as the desktop Gallery (App.axaml):
  a dark blue-slate instrument panel, hairline-ruled panels, condensed DIN-style labels, monospaced readouts,
  and colour taken only from the four dye channels of Sanger chemistry (A = FAM green, C = Cy5 blue,
  G = HEX amber, T = ROX red). Amber doubles as the indicator lamp: the one action and the one selection.
  Signature: a chromatogram ribbon in every page header, drawn from that page's own sequence, which sweeps in
  like a capillary read when the page changes.
